' L To all whom it may concern: I j Be it k h we, CLAY VAN SILER- and BENJAMIN H. PURCELL, citizens of the United States,,residing at Terre Haute, in the county of Vigo and State of Indiana, have invented a new and useful Leer-Door,

' of which the following is a specification.

. v1ce;-Fig. 2 is aside elevation; Fig. 3 a plan; and Fig. 4 afragmentary plan with the relative thicknesses considerably. exag- In the drawings, 8 indicates the leer, which is mounted,-in the usual' manner, .the

.receiving belt 9.- The mouth of the leer is of the usual rectangular form and arranged .to close this month are a series of L-shaped plates 10, 10, 11, 11, and 12, which are iden tical in size and shape. Plates 10, 10 are pivoted at 13, 13 at'opposite ends of the mouth of the leer. These two plates 10, 10

are arranged in. the same vertical plane, 30.

and their pivots 13, 13 are-carriedby the supporting bar 15. Plate 12 is pivotally supported at 16 in a verticalplaneimmediately adjacent-the plane of plates 10, 10,

. the pivot 16'being carried by bar 15. One

plate '11 is arranged ina vertical plane *immediately behind theplane of plate 12,

-' while the other plate 11 is arranged in the vertical plane immediately behind the plane, of the-first'mentioned plate. 11, and the two plates 11 .are"'supported by pivots 17, 17 carried by aframe bar 18, which'is parallel with bar-15 andis spaced therefrom a dis-.

1 tance equal to four thicknesses of the plates 10, 11 and 12. The arrangement of the several plates 10, 11 and 12 is such that their depending arms. overlapeach oth'er and close the mouth of the leer except for a space, the lateral dimension of which is a little less than 'the width of anyone of the arms. Thepivots 13, 16 and 17 are so placed that the crotch between the inner edges of the 'two arms of each plate will be slightly above the mouth of the leer. t

Projected into the mouth ofthe leer is a Specification of Letters Patent. Patented 15 1918,

Application filed November 17,1917. Serial No. 202,577.

feedin chute 25, which is adapted to engage t e adjacent. inner edges of the plates 10, 11 and 12. Chute 25 is designed to be moved laterally, first in one direction and then in the other, and, as it moves, it will progress into engagement with the dependmg arms of the cover plate and swing said I depending arms forwardly a'nd upwardly;

- This will cause the horizontal arms of the .plate to move downwardly, so as to drop in ticles for deposit in the leer are delivered to the chute, is immaterial and forms no part of our present invention. For the sake of completeness, we have illustrated somewhat generally automatic mechanism for handling the delivery chute 25. This mechanism comprises a carriage 28 which carries the chute 25 and is driven first in one direction and then in the other by a driving screw 29, controlled by reversing drivinggearing 30. Carriage 28 carries a transfer wheel 31, which serves to. transfer chute 25. 1

In order to limit the swinging movement articles 32 fromthe delivery -belt"33 to the of the plates 10, 11 and 12, each plate is I provided with an arc-shaped slot 35 rej ceiving a stationary pin 36.

We claim as our invention:

1. The combination with a chamber hav ing a receiving opening, of a loading member movable laterally in said opening, and a plurality of-overlapping L-shaped' p tes'arranged in a series substantially the opening into'the chamber and coiiperating' with the loading member, substantially as described. v I

2. The combinationwith a chamber having a receiving opening, of a loading member'arranged to traverse thereceiving opening laterally, and a plurality of movable plates arranged to close the receiving opening'and to successively cotiperate with the loading member to be successively shifted vering .out of and into closing positon by the lat-' eral movement of the loading member.

3. The combination of a leer-loading and to be engaged'by the loading member member shiftable transversely and a plu-. to be swung about their pivots into succesrality of leer-closing members successively sive leer-closing position. cooperating With the loading member and In Witness whereof, we have hereunto set 5 movable thereby successively into and out our hands at Terre Haute, Indiana, this 15 of leer-closing position. 7 12th day of November,'A.
